Violin sounds flat and disgusting?

So I'm recording tomorrow along with a flute and clarinet, a piece we wrote. I've only been plying it for a few days but the wound is wonderful when I hear it first hand as I'm playing it. I decided to record it using Voice Memos on my iPhone 5s but the moment I played it back, it played flat and awful. It ashamed me that I'd been playing that out loud for my entire family for 2 days straight.
It's not just the piece, anyone I try, even famous ones with great melodies, sounds great to me but is actually disgusting being recorded.
How can I improve my playing so it sounds good on recording? Or do I need a better recording device?

Problem with iPhone storage?

NOT ICLOUD STORAGE -- STORAGE ON ACTUAL PHONE

iCloud storage is fine since I rarely ever use it. On phone storage though, phone said I used all 5 gb of data, but I tried deleting apps and pics, but didn't work. My dad said he has same problem. Mom and brother don't have this problem. *NOTE - we're all together on family plan*

With me though, I tried re-setting but that also did not work -- never cleared up anything with data on phone. Not sure why though since all the other times it did work except for now.

Will Apple Replace my Iphone that randomly stopped working?

I don't have my iPhone protected under warranty, but my phone stopped working for no reason.
At first it wouldn t turn on so I plugged it into iTunes and it told me to update my phone which I did. After that, it would turn on but the screen would immediately turn blue then restarts and continue on that cycle repeatedly. It stopped doing that after about 5 minutes so I thought it was okay and I went to sleep. When I woke up in the morning the screen was black and I plugged it into Itunes again where it said to restore my phone, but everytime I tried and error occurred and told me they could not restore it.
